templatefuncs: only render text portion of minirst.format() result When "keep" argument is provided, the function returns (text, pruned), where pruned is a list of sections from the original plain text that were pruned from the rendered result. Let's not output it together with the rendered HTML.

tests: demonstrate that hgweb renders "pruned" that minirst.format() returns Notice at the bottom of the help text there's "windows". It's a section that is in the original help text, but was pruned (because hgweb didn't ask for it).

rebase: avoid RevlogError when computing obsoletenotrebased (issue5907) The key to reproducing this seems to be missing an obsolete node that is not an ancestor of the destination.

rebase: prioritize indicating an interrupted rebase over update (issue5838) This should also cover the transplant extension, and any other non clearable states.

tests: demonstrate inconsistent messaging around interrupted rebases

tests: adapt test-check-pylint to run on Windows The line endings are explicitly converted because this was ending up with '\r (no-eol) (esc)' lines, in addition to the usual '\r (esc)' lines. I've seen the fakerc output on other recently installed systems though (10.13 and/or Fedora 26). Unfortunately, the output here uses '\\' on Windows, so glob away the whole path.

hghave: avoid a deadlock reading the child process's output The output of `pylint` is voluminous enough that it fills the buffer on Windows, and waited for the parent to read it out. But the parent was waiting on the child to exit. I'm not sure what the intent of setting `ret = -1` in the exception handler just above this was...

lfs: bypass wrapped functions when reposetup() hasn't been called (issue5902) There are only a handful of methods that access repo attributes that are applied in reposetup(). The `diff` test covers all of the commands that call scmutil.prefetchfiles(). Along the way, I saw that adding files and upgrading the repo format were also problems (also tested here). I don't think running `hg serve` through the commandserver is sane, but I conditionalized both the capabilities and the wsgirequest handler because it's trivially correct. It doesn't look like there has ever been a caller of candownload(), so there's no test for that path. The upload case isn't testable, because uploadblobs() bails if there are no pointers. The requirement should be added any time pointers are introduced, and that would force the extension to be loaded specifically for the repo. This covers `debuglfsupload`, the pre-push hook (which isn't set until the repo is promoted to LFS), and uploadblobsfromrevs(), which can be called by other extensions. I think readfromstore() and writetostore() are only reachable as a flag processor for revlog.REVIDX_EXTSTORED, and a requirement is added as soon as that is seen, so I don't think those are a problem.

revlog: disallow setting uncompressed length to None Backed out changeset a4942675de6b

unionrepo: fill in uncompressed length of revlog entry It can be either -1 or a valid length, but shouldn't be None. IIUC, we can simply trust the length retrieved from the revlog to be overlaid. I don't bother thinking whether the compressed length can be copied as well. We'll need to fix it later.
